Our C7 Corvette Z06 Stage 3 Performance Package is where the gloves start to come off and reveal the true potential of your LT4 powered Corvette.  This package goes beyond our Stage 2 Performance Package by adding a Synergy Motorpsort Heat Exchanger and Expansion tank, ATI harmonic dampner, DSX Tuning lower pulley, Katech thermostat, and Brisk Racing spark plugs.  This kit utilizes the previous packages ability to let the engine breathe now allowing us to add boost while the heat exchanger and expansion tanks allow us to keep temps down and keep the supercharger in it's efficiency range. This package starts at $7,499.99 with parts, installation, and dyno tuning!

A combined 40 year experience can guarantee our customers we have the knowledge to give them the quality of work they expect.
